Image Compressor
Compress any JPG, PNG or WebP image in your browser. Drag a quality slider and watch the file size drop in real time — nothing leaves your device.
How It Works
Reduce image file size while keeping quality, with a live quality slider. Everything runs the moment you upload an image — there's no queue, no account, and no watermark on your download.
How to Use Image Compressor
- Upload your image (drag & drop, tap to browse, or paste from clipboard).
- Adjust the settings if needed.
- Click the process button.
- Compare before and after, then download your result.
Supported Formats
JPG, PNG and WebP are supported. Files up to 30MB are accepted.
Why Use Image Compressor
Image Compressor gets a common image job done in seconds without installing desktop software, creating an account, or waiting on a slow upload queue. Your image is processed directly in your browser. It never leaves your device.
Tips
- For the smallest file size, start from the highest-quality original you have.
- If you need an exact pixel size for a form or platform, check the presets on our Image Resizer.
- Chain tools together — for example, resize first, then compress, for the smallest possible result.
FAQ
Is Image Compressor really free?
Yes. Image Compressor is completely free to use, with no signup, watermark or hidden limits on how many times you can use it.
Is my image uploaded to a server?
No. This tool processes your image entirely inside your browser using the Canvas API. Your file never leaves your device.
Will compressing reduce quality?
Some quality loss is a normal trade-off of reducing file size. Use the quality or color-palette slider to find the balance that looks right for your use case.
Does this work on mobile?
Yes — every PixelFree tool is built mobile-first and works on iPhone, Android, tablets and desktop browsers.
What this compressor actually changes
This page reduces the number of bytes in a still image. It does not add sharpness. JPEG quality is lowered first. If the file is still large, the long edge can be reduced. PNG graphics with few colors respond better to palette reduction than to JPEG-style quality sliders.
Use this page instead of the old 50KB / 100KB / 200KB URLs. Pick a target that matches the form you will upload to. A visa portal that caps attachments at 50KB needs a harsher setting than a product gallery that allows 400KB.
Worked example
A 12-megapixel phone JPEG of 4.2MB often falls near 180–250KB at quality 70 without resizing. Reaching 50KB usually requires a smaller width and visible softness on text. If a document must remain readable, raise the size cap or photograph the page again closer and flatter.
When not to compress
Do not run this tool as the last step on a file you still need to crop or convert. Compress last. Do not compress a logo that must stay razor-sharp; use SVG or a small PNG instead.
